  1. *Kinetic parameters: Yp/s = mg L-dopa produced/mg substrate consumed, Qs = mg substrate consumed/ml/h, qs = mg substrate consumed/mg cells/h.
  2. **2.0 mg/ml diatomite added 15 min after the start of reaction.
  3. $Acetate buffer
  4. *$<p> is for significance level (≈0.05) on the basis of probability. HS denotes that the values are highly significant.
